Application filed July 17,1906. Serial No. 326,533.

Be it known that we, J OHN T. GLAZIER and CoLUMBUs C. PARKER, citizensof the United States, residing at Indiana olis, in thecounty of Marionand State of ndiana, have invented certainnew and useful Improvements inWindow-Ventilators, of which the following is a s ecification.

The object this invention is to provide a ventilator attachment for theWindows of railway cars, residences and other buildings whereby thecurrent of air passing therethrough can be regulated.

Another object of the invention is to provide partitions for separatingthe-airpas'sage through the ventilator into compartments to compel theair current to take a circuitous course through the device and to soshape the partitions as to remove dust and other foreign substances fromtheair before itis admitted into the room.

A further object of the invention is to provide a Water pan at'thebottom of the air chamber and to provide conduits or ways in thepartitions to conduct the dust and foreign particles into the Water.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

In the drawings, Figure 1 is a perspective view of the lower part of awindow viewed from the outside, with the ventilator in place.

Fig. 2 is a top plan view of the improved ventilator showing parts ofthe latter broken away to illustrate the inside construction.

Fig. 3 is a transverse vertical section on the line 33 oi Fig. 2, andFig. 4 is a section on the line 44 of Fig. 3. 4

Like characters of reference indicate like parts throughout the severalviews of the d aw ngl 5 isthe window easing-and (3 thc' wind'ow sash,both of usual construction The sash is shown as partly raised to providea space in which this improved ventilating device is placed. .Theventilator comprises :1 rectangular box or case 7 with longitudinalslots '8 in two opposite vertical sides of the box.

These slots or openings are protected by the.

hoods 9. 'lransvcrsc partitions 10 10 set off "a middle compartmentwhich the air current side of the uilding. Slideways are formed in theends of the bOX7 out side of the partitions 10 to receive the endsof thesections 12 which are longitudinally adjustable in the slideways abovementioned, for-.the piur h o t e which the ventilator is to be used. Aflange 14 extends along the innecsideiof,the lpper face of theventilator to. make a better joint against the sash 6 which will belowered upon the ventilator in close contact. with said flange. v i

I Referring to Fig. 3, 16 is a water pan at the bottom of the airchamber, and 17. and 18 are partitions for dividing the box intocompartments. The partition 17 preferably terminates in the water of thepan 16 so as to form a sealto prevent the passage of air under thispartition, butterminates sutlicientlv below the top of the box 7 toleavean air passage from one side "of the partition 17 to the other.The'partition -18 makes a close fit against the top ofbox .7 but doesnot extend to the bottom ofthe boxand the. space 'thus left at thebottoinioriiis a passageway for air under said partition. l he.partitions .17 and 18 are formed outof corrugated'sheet metal, thecorrugations extending-from the side edges of the partitions in anoblique upward direction to the vertical midline of the plate, as shownin Fig. d and the. partitions are set at an oblique angle, as shown inFig. 3. The'result of this, constructionis that air commg in from theoutside of'ihe buildingand doadedwith (lust and oth er impurities willbeat against the corrugations on the oblique under-sides ottlieplatescausing nucl oi the passes from the outside to theinose foreign matterto be removed, and this dust srancli other substancesil alli-ng ipo ithe corrugations of 'tiheupper sides olbtl e partitions will be carriedto the edges ol the plates and thus removed from their ini'ddlesiivhercthe largest volume of. the ziir passes. This is particularlv true; ofthe plate 18; In this, as shown in Fig. 4t, the aiitpassageis largest atthe 'middle of the plate andlinostofthe dust will be directed by thecorrugatioiis to the air pasisi ng under the plate.
